UNITED STATES PATENT OFFICE 2,039,741 v VACUUM-CLEANER DUVST BAG Henry I. Richards, Washington, D. C. Application December 10, 1932, Serial No. 646,682

Claims. (Cl. 18351) 'I'his invention relates to dust' bags for vacuum cleaners and more particularly to a. dust bag in which the dust collected may be readily and cleanly disposed of.

5 An. object of the invention is to provide a 'means for emptying the dust from the cleaner bag without scattering it about and without soil ing the operator as is necessary when dust bags are emptied by the present practice of shaking. 10 A further object of the presentinvention is to construct an improved dust bag in which the dirt and dust lare collected in an easily disposable, self-supporting containerwhich is readily removed through a side wall of the bag. In the drawings, Fig. 1 is a. cut-away view through'the side of the bag.

Fig. 2 is a cut-away view through the back of the'bag.

Fig. 3 shows the bag `attached to the handle and open for insertion of the dust container.

Fig. 4 shows details of the container construction.

Fig. 5 is a horizontal section on. line'S--S ofA Fig. 3.

Fig. 6 is a vertical section of a modification o the dust container. Fig. 7 is a detail view of the paper dust bag. 'Numeral I denotes generally an elongated porous fabric dust bag for vacuum cleaners, the y to the outlet conduit of a conventional suction.

cleaner, (not shown).

As indicated in Figs. 1 and `2, the nozzle 6 is fitted' at -the end of an interior discharge 40 pipe 1, preferably composed o'f some suitable smooth nish or glazed material to which particles of dust will not adhere. 1 may be completely within the bag as in Figs. Vl and 2 or it may be sewed into the side wall of the bag as in Fig. 5. In either case the discharge end of the tube 1 is some distance above the bottom of the dust bag. It is customary to construct these elongated flat bags of exible.

porous fabrics which expand on receivig air from the blower of the cleaner and permit the air to slowly diifusewithout allowing dust to sift through.

The bagv I, see Figs. 1 and 3, has a side opening 8 formed therein and is normally closed by sliding keeper 3 encircling the edges of the open-I.

I'his inlet pipe Y bag I adjacent the opening 8 is a strip ofspring 5" metal I0 extending from the edges of the openfing 8 around the inner periphery of the bag or over to the inlet /pipe 'I. .In either formation, however, it will be observed that the band or strip I3 is slightly below the dischargeend of '10 the inlet tube 1.

At the lower edge of the opening 8 a strip of metal I I sewed in the lower portion of the bag extends across the same as in Fig.` 5 or over to the inlet pipe I as in Fig. 1. 15

The salient'feature of the invention isthe removable dust collection receptacle I2 composed of paper or other suitable material and tted in holder I3. This holder I3 may be made of spring metal in the form 'indicated or any other suit- 20 able configuration. As illustrated in Fig. 4, an

elliptical spring metal band I 4 has a. U-shaped strip I5 attached to it. In this frame a paper I bag I2 is mounted withvthe bottom of the bag resting on the U-shaped strip and the upper 25 n edges are folded over the band I4.

It will be readily seen that the receptacle I2 is adapted to be inserted interiorly of the dust bagv I through side opening 8. When inserted, the bottom of the frame I3 rests on strip Il 30 and, when the tube or keeper 9 is slid down over the edges of the opening 8, the elliptical band Il of the frame carrying the folded over receptacle I2 will bind tightly against the interior spring strip I0 and seal the receptacle in the bag 35 adjacent to and slightly below the discharge inlet 'I.

Thus, when inuse, the incoming dust-laden air from the cleaner discharges interiorly of the bag I above the receptacle I2 and, as the air 40 pressure within the bag diffuses, the dust settles or gravitates into the receptacle.

' When it is desired to remove the accumulation lof debris, the cleaner motor is shut oi and the merely dumping it. z 55 Inasmuch as it is customary to disconnect the no zzle 6 when emptying the bag (as shown in Fig. 3), a ilap I6 is stretched interiorly of the bag I above the discharge tube 1. This ap I6 is blown out of the way by the blower when the cleaner is in operation but falls over the mouth of the tube I when the motor is cut oiI. Consequently,

obvious that when the tray is removed from the cleaner it is merely necessary to fold over ilap 22 and tie cord 24 around button 23 so that a compact closed package of dbris is formed which may be handled without spilling any of the contents.

What I claim is: 1. In a dust bag for vacuum cleaners, a porous bag having an inlet attached to the cleaner, a

horizontal open tray completely wthins'aid bag positioned adjacent the inlet adapted to receive dust therefrom and an opening in one side of said bag for the removal of said tray.

2. A dust bag for suction cleaners vhaving an opening in one end of the bag for the ingress of dust-laden-air, a side opening formed in an intermediate portion of the bag, a clamping device secured in the bag adjacent the opening, and-a removable receptacle adapted to be retained inte s riorly of the bag by the clamping device.

' 3. lAvdust bag for vacuum cleaners including a porous vbag body, an inlet attached to the cleaner and discharging interiorly of the bag body, a closable opening in the body opposite the end of the inlet, a split resilient ring secured circumferentially in the body, and a removable dust receptacle Y held in place by said split spring ring.

4. `A dust bag for vacuum cleaners including a porous bag body, an inlet attached to the cleaner and discharging interiorly of the bag body, a closable opening in the body opposite the end of the inlet, a split resilient ring secured circumferentially in the body, and a removabledust receptacle positioned slightly below and to the lside of said inlet discharge and held in place by said split spring ring.

5. In a vacuum cleaner bag, a tubular dust inlet, an opening in the bag, a closure therefor, a spring metal strip circumferentially secured in the bag at the opening, and a receptacle-carrying frame rmly held in the bag by the split ring an 6. A vacuum cleaner, including a dust receiving bag, a removable dust receptacle for said bag, said removable dust receptacle comprisingA a metal frame, a liner therefor, and means for securing and positioning the metal frame and liner within the cleaner bag.

'7. In a vacuum cleaner bag, a removable dust receptacle in said bag, the said dust receptacle comprising a metal frame, an open top liner therefor, and means interiorly of the cleaner bag for securing and positioning the metal frame and liner within the cleaner bag.

8. A vacuum cleaner bag comprising a porous body, a dust inlet tube aiiixed at one end thereof discharging into the bag and a removable dust receptacle positioned in the body of Asuch a size as to completely block the body adjacent the discharge end of the inlet.

9. A vacuum cleaner bag comprising a porous body, a dust inlet tube afiixed at one end thereof discharging into the bag and a removable dust receptacle positioned in the body of such a size as to completely block the bottom portion of the body adjacent the discharge end of the inlet.

10. A dust bag for vacuum cleaners comprising a substantially fiat elongated flexible bag, an inlet tube at the lower end thereof discharging dustladen air interiorly of the bag, an opening in one side of the bag,'a fiat strip fastened in' the bag from the lower edge of the opening across to the tube, a split circumferential strip fastened in the 'bag' from the upper edge of the opening around the interior and slightly below the discharge of the inlet, a receptacle adapted to be rmly retained inthe bag by the circumferential and flat strips and receive dust from thel inlet discharge.
